Abstract
Thermal media comprises a substrate having a front side and a back side opposite the front side. The thermal media also comprises a thermally-sensitive coating disposed on the front side of the substrate. The thermal media further comprises a cleaner material disposed on a portion of the thermally-sensitive coating. The cleaner material is integrated into the thermally-sensitive coating to perform cleaning of a thermal print head when the cleaner coating moves past the thermal print head.
Claims20
A thermal media comprising:
- a substrate having a front side and a back side opposite the front side;
- a thermally-sensitive coating disposed on the front side of the substrate, wherein portions of the thermally-sensitive coating are adapted to be imaged by a thermal print heat to provide receipt information as the substrate moves past the thermal print head;
- and
- a cleaner material disposed on a portion of the thermally-sensitive coating and adapted to perform cleaning of a thermal printhead when the cleaner coating moves past the thermal printhead.
1 more element
Self-cleaning thermal media comprising:
- a core;
- and
- a web having a longitudinally-extending axis and wound on the core along the axis, the web including (i) a substrate having a front side and a back side opposite the front side, (ii) a thermally-sensitive coating disposed on the front side of the substrate, and (iii) a cleaner material disposed on a portion of the thermally-sensitive coating, wherein the cleaner material functions to perform self-cleaning of a thermal print head, without using separate materials, when the cleaner material moves past the thermal print head.
A method of manufacturing self-cleaning thermal media, the method comprising:
- applying a thermally-sensitive coating on a front side of the substrate;
- and
- applying a cleaner material on a portion of the thermally-sensitive coating such that the cleaner material performs self-cleaning of a thermal print head when the cleaner material moves past the thermal print head.
